My invention relates-to locking means Imore especially intended for fastening the hatch cover or' a railroad refrigerator car; saidV means being adapted to receivethe usual typesfoff car seals at present employed.

The invention has for its object the proyision of a locking device which may be readily applied te railroad cars at presentin use without alteration in the hatch closure vconv struction; and wherein the vlocking means is associated with the usual staple element of the hatch locking means s as to practically constitnteqa-n integral part thereof and reTv moyal of the locking element, after the staple hasrbeen securedfin place, is made impossible my improved means in lend elevation and` shown in locking position; A z

./FigureQ, is a top plan viewer my irnprovedrneans in locking' position and a portion of'afhatch cover.

Figure 3 is a perspective view of my improved locking-means.` rThehatch covers of railroad refrigerator` cars are usually provided with hasps secured thereto so` Vas to have the freeends of the has'ps extend beyond the free or movable ends of the hatch covers; the hasps being v formed to cooperate either'with a swinging lever secured to the car-roof or witha suitable. staple member secured to the car-roof adjacent to the free endv of the hatch closure. The lastmen-l shown at 11, thus lnaling it impossibletoraise this end'of the hatch cover. y For, purposes ,of 'exempliiic'atiom I have chosento illustrate ymy invention with this p typelof l'ref'rigeratfor car hatchclosure,I al.-`

though `it will be understoodthat the invention is equally applicable tof other types of hatch` closures :as Ywell Vas 'forjlockingl other devices. s s Y 1 f In the drawinglthe hatch cover is shown Providedfwth hasn 12,911@ end, whereof is secured in place by bolts as' at r13; the hasp intermediate ofv its endsV being bent down?,v

Ward'ly over the free end of the hatch ,coverl and thence disposed 4'lfelalll'y so as to extend substantially parallelwith the car-roof, a

portion whereofis shown at le. The `type ohasp here shown is intended for use with af staple which is usually bolted or `Qtljierwise fastened to the car-roof; the free end of thev haspibns provided with 21 Staplelecvne Y slotl'asshown at 15 in Figure 2.A l v My invention contemplates acombned sta-- pleand-leelnellnent .Carry-ine member .16, which. is adapted to be substituted fel* 7the Qrdnarystanlefat prsent employed? "My improved member 1.6 comprises a sta:- plfeportion 17 having theapfertured llaterally disposed base 18`wherebythe member .is bolt?, ed f orV otherwise secured: to the rar-roof: 14 adjacent to, ythe .hatch with "the @Standing staple portion 17l ,disposed .in a vdirectiontransversely of the car-roofsof as to registerv with and passfthrOugh the slot 1-5- of the hasp' 12 when the hatch cover 10 -is cl'osedpos'ition as Shown.

f The basellS, on onelongitndi-nal side, preferably on the side disposed towardthe hatch, is provided-with an integral laterally disposed extensionwhich terminates inthe ver.- tical enlargement or upwardly disposed head 19. This head 19 is provided with Van opening 20 extending transversely therethrough and substantially parallel with the opening 21 inthe staple portion" 17." lOne side of the opening 20;,namel`y the upper side, isprovided with the upwardly disposed slot 22 for the purpose-hereinafter described.

l My improved lockingelement is preerably in thenature ofa U'shape hook 23 provided with a short leg 24 which is intendedto pass through the hole 21 of the staple portion 17, while the long leg or side of the hook mem ber 23 is slidingly mounted in the opening 20 in the head 19.

The long leg or side of the hook member 23, adjacent to its ends, is `provided with a pair of lateral enlargements or lugs 25, 26. The lugs 25 and 26 are arranged in alignment and are of configuration and dimensions to match the slot portion 22 of the opening in the head 19, so as to permit the long leg or side of the hook member 23 to be inserted through the opening of the head 19 when the hook member is `positioned with the lugs 25 Yand 26 arranged in registeringalignment with the slot 22.

It is apparent from -the construction shown that the aligned position of' the' lugs 25 and 26 with the slot 22 can only be obtained when the hook member`23 is moved to a position where the short leg or side 24will be disposed in a plane beneath the base 18 of the device, and therefore a position which can Vbe obtained only before the device is secured to the car-roof, as the lugs 25 and 26 are arranged substantially in the same plane as the intermediate portion and the short leg or side 24; while thejslot 22in the head 19 is disposed upwardly as shown in Figure 3. The hook member 23 is inserted through the opening 20-22 before the device is applied to the car-roof; the insertion being accomplished by 'swinging the short leg 24 downwardly beneath the head 19 so 'as to present the lug 25 of the long leg or side upwardly Where it will register with the slot portion 22 of the opening 20 in the head 19.

After the lug 25 has been passed through the opening in the head 19, the hook member is thenv swung upwardly, which causes the lugs 25-26 to be moved ninety or Vmore degrees away from the slot 22 and hence prevents withdrawal of -the hook member 23. v

` As soon as the base portion 18 of the device has been secured to theV car-roof by bolts or other fastening means passed through the holes 27, 27, it is apparent Athat the hook memt ber 23 cannot then be swung into a position where `the lugs will register with the slot and hence the locking hook becomes an integral part of the device and accidental dissociation of the elements is impossible.

The lug 25 prevents withdrawal of the i hook member; While the lug 26, which is located to the opposite side of the head 19, is intended to properly position the short leg or side 24 relative to the staple 17 so that 6.0 opposite ends of a diagonally arranged slot 28 in leg 24 will be positioned to opposite sides of the staple member 17 when the hook member is in locking position. The slot 28,

which extends through the hook member, is intended to receive the usual seal, generally consisting of a, wire or metal strip, the ends whereof are brought together, after the wire has been inserted through the slot, and then soldered or sealed together.

To lock the hatch closure, the hood member 23 is slid along in the head 19 until the lug 25 engages the side of the head 19, at which time Athe short leg 24 will be out of engagement with and free of the staple 17, thus allowing the end of' the hasp 12 to be passed over the staple 17. The short leg or side 24 of the hook member is then passedthrough the staple 17 above the end of the hasp and the usual car seal (not shown) is then arranged as previously stated.

Vilhat I claim is:

1. Locking means of theV (character described comprising a single 'piece member provided with an attaching base; an upstanding staple portion disposed transverse-Y ly o and integral with the base; a laterally disposed extension integral with one side of the base and terminating in an upstanding enlargement provided with an opening therethrough arranged parallel with the opening in the staple portion andy a vertically arranged slot communicating with the opening in the enlargement; and a U-shaped locking memberk with sides of unequal length, the long side of the member being slidingly mountedl in the enlargement while the short side is adapted to pass through the opening in the staple portion, the long side of the locking member adjacent oppositeends being provided With parallel extensions disposed in the same plane as the short side of the locking member whereby movement of the locking member in locking and unlocking directions' is controlled, the slot in said enlargement being disposed beyond the arc of movement of the locking member when the single piece member is secured in place.

2. Locking means of the character described comprising an upstanding head vportion provided with an opening transversely therethrough of irregular formationg" a U-shaped locking bolt having legs of unequalv length, the long leg being slidable in the opening of said head and provided adjacent opposite ends with laterally disposed enlargements arranged in alignment with each other and in the same horizontal plane as the short leg, said enlargements being formed tol match the irregular part of said opening, said enlargements and the matching portion of the opening being arranged at an angle to each other relative to the oscillatory movement of the locking bolt with the Vmatching portion of the opening arranged beyond the arc of movement of the bolt when the locking means is secured in place; and a staple whose opening is disposed parallel with the opening' formed to constitute an upstan'ding apertured staple portion and an extension disposed laterally from one side of the staple portion and terminating in an apertured head, the aperture in the head involving a radial slot; and a U-shaped bolt having legs of unequal length, the short leg being adapted to pass through the staple portion vvhile the long leg at opposite ends has lugs disposed laterally and parallel with each other and with the short leg, said long leg being slidably mounted in said head and one of said lugs adapted to pass through said slot before the member is secured in place, the slot being disposed beyond the aro of normal movement of the legs whereby sliding movement of the bolt is limited and Withdrawal of the bolt from said head made impossible after the member has been secured in place; the short leg of the bolt being provided with a diagonally arranged slot Whose ends are adapted to be disposed at opposite sides of the staple portion, when the bolt is in full locking position, to receive a sealing medium.
